Proto-Sinaitic (also referred to as Proto-Canaanite when found in Canaan, or Early Alphabetic) is found in a small corpus of c. 40 inscriptions and fragments, the vast majority from Serabit el-Khadim in the Sinai Peninsula, dating to the Middle Bronze Age. They are considered the earliest trace of alphabetic writing and the common ancestor of both the Ancient South Arabian script and the Phoenician alphabet, which led to many modern alphabets including the Greek alphabet. According to common theory, Canaanites or Hyksos who spoke a Canaanite language repurposed Egyptian hieroglyphs to construct a different script. The earliest Proto-Sinaitic inscriptions are mostly dated to between the mid-19th (early date) and the mid-16th (late date) century BC.

The Ihre-Götlin Runic inscription is one of the other runic inscriptions in America. I couldn't find much data on it.

Stampede was created from a small sample of letters found on an old document dating back to 1902 from the Chicago, Indiana & Eastern Railway Co.
